Republicans make a push in PA - 21 News Now, More Local News for Youngstown, Ohio -

MERCER COUNTY, Pennsylvania – On Sunday, Governor Mitt Romney made his first campaign stop in Pennsylvania since September.

Although past polls have predicted that Keystone voters would go for President Obama, Republicans are still hoping to win the Commonwealth's 20 electoral votes.

At the Republican headquarters in Mercer County, volunteers worked the phones and offered rides to the polls while others were on the radio working to get every vote for the Romney- Ryan and Republican ticket.

Ginny Richardson, Chairman of the Mercer County Republican Party, says the grassroots campaign has been working for months on behalf of Romney.

"Pennsylvania seemed to be the biggest secret across the nation as far as what we were doing grassroots and our grassroots activities are now paying off because they have stepped up and are noticing Pennsylvania. And I think when tomorrow night's votes are counted you'll find out Romney is on top in Pennsylvania," Richardson said.

At the Obama headquarters in Sharon, workers are trying to get voters motivated to head to the polls to give President Obama four more years.

"Pennsylvania is going to be a very important state. We have volunteers out knocking on doors, hanging flyers on doors. We have people making calls for what we call the get out the vote effort. Making sure everybody understands how important just a few votes is in each precinct," said Obama volunteer Chuck Baldoff.

Both campaigns are not slowing down. Governor Mitt Romney will be working to shore up support in the Keystone State with a campaign stop in Pittsburgh on Election Day.
